The former Celebrity Big Brother winner revealed her dramatic transformation in a fuchsia bodycon dress which highlighted her now slender frame as she signed copies of her DVD 3 Minute Belly Blitz.

Charlotte greeted fans and said that she “loves coming to Liverpool”.

She added: “Whenever I come to Liverpool for appearances or to just have a good time, there is always a great response from my Scouse fans, I love it.”

Charlotte has lost an incredible two-and-a-half stone and she believes that because the sections in her DVD are a maximum of three minutes long, her fans “won’t dread working out.”

The reality star added: “There is a cardio section, but there are also videos which focus specifically on various muscle groups and body parts meaning that you can pick and choose what you want to work on each day.”

“You also don’t have to work out to the sections in a specific order so you can always mix it up.”

The 24-year-old Geordie lass has revealed that she will be appearing on MTV’s new series of Ex On The Beach alongside her on-off boyfriend and fellow Geordie Shore castmate Gary Beadle.

Talking about how she will keep up her fitness regimes both inside the Geordie Shore house and whilst filming Ex On The Beach she said: “I managed to do my 3 Minute Belly Blitz DVD whilst I was in the house during the last series because it would literally take just 12 minutes out of my day to do four different workouts.”

“I also have to eat healthy, but the exercise definitely does it for me. I think if I didn’t stick to my 3 Minute Belly Blitz I would see the weight piling back on.”

But the main reason why Charlotte can keep the weight off is due to her new found confidence.

She said: “I feel so much better in myself now, I would never go back to how I was before.”
